IMPROVEMENT IN HEATlNG-STOVES.

Specification forming part of Letters Patent No. 197,680, dated November27, 1877 application filed June 9, 1877.

To all whom it may concern:

Be it known that we, DAVID STUART and LEwIs BRIDGE, both ofPhiladelphia, Pennsylvania, have invented anew useful Improvement inHeating-Stoves, of which the following is a specification:

The object of my invention is to make a cheap heating-stove, bycombining a casing, having flat front and rear of oval shape with sidesconforming thereto, with a fire-place, grate, and ash chamber extendingfrom front to rear of the casing, all as described hereinafter.

In the accompanying drawing, Figure 1 is a vertical section of ourimproved stove; Fig. 2, a transverse vertical section; Fig. 3, asectional plan on the line 1. 2, and Fig. 4, asectional plan on the line3 4.

The outer shell A of the stove is made oval in shape, and has oppositeflat sides a, and a. Within this outer shell is contained a casingcomposed of opposite plates b b and bottom plate d, all of which platesextend from the front a to the back a of the outer shell. This innercasing is separated by a grate, h, into the quadrangular fire-pot E,which is lined with refractory tiles, as usual, and the ash-chamber F. 1

Immediately above the fire-pot is the magazine G, which passes throughand is secured to the top of the outer shell.

Two diving-flues, H H, are formed by and.

between the outer shell and inner casing, and these flues unite with theflue I between the bottom plate (I of the said casing and the base B,the products of combustion from the diving-flues passing through thisbottom flue, thence through the vertical flue J, formed by I aprojection on the back plate of the stove, and thence through theexit-opening m, di-v rectly opposite which, and in the back plate a, isan opening furnished with a damper, n,

' an opening through which the products of comfire-pot to, thediving-flues, at which point they are most brilliant, will be seenthrough the said windows.

The communications of the diving-flues with where they are most neededbefore they pass into the bottom flue I.

These deflectors t t are, in the present in stance, continuations of theopposite side plates 1) b of the inner casing.

We prefer to arrange a grate, i, Fig. 2, at the front of the fire-pot,and to make an opening in the front plate a of the stove directlyopposite this grate, a door or frame, q, with mica windows, being fittedto the opening, so as to give the stove as cheerful an aspect in frontas it has at the opposite edges.

There are also in the front plate of the stove doors at, w, and y, thefirst adapted to an opening through which access can be had to thecombustion-chamber, the second for the ash-drawer opening, and the thirdforthe opening through which access may be had to the bottom flue I.

It will be seen, without further description, that although the stove issimple and inexpensive as regards construction, it presents an extendedheating-surface.

We claim as our invention- A stove in which a casing, consisting of aflat front and rear of oval shape, or shape approximating thereto, andsides conforming therewith, a fire-place, E, grate h, and ashchamber Fcontained within the casing, and extending from front to rear of thesame, are combined, all substantially as set forth.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
